What are the 3 main types of galaxies?
Galaxy classification There are three general types: elliptical, spiral, and irregular.
Perhaps the most familiar kind of galaxy are spiral galaxies..
Are there galaxies we Cannot see?
96.7% of the galaxies that we can observe today are already gone. 98.6% of the galaxies that we will ever observe are already gone. And only, roughly, 66 billion galaxies are still reachable by us today.
What is Earth’s galaxy called?
the Milky Way GalaxyOur Sun (a star) and all the planets around it are part of a galaxy known as the Milky Way Galaxy.
How long until we Cannot see galaxies?
A rough calculation shows that this happens when the structure is around 14 billion light years distant. From that point in time onwards, any light emitted by the structure will no longer be able to reach us.
Can you see the Milky Way with your eyes?
More than 100,000 light years in diameter, with more than 100 billion stars and at least as many planets, the Milky Way is arguably the most impressive feature of the night sky that you can see with the naked eye.
Will we ever travel to another galaxy?
The technology required to travel between galaxies is far beyond humanity’s present capabilities, and currently only the subject of speculation, hypothesis, and science fiction. However, theoretically speaking, there is nothing to conclusively indicate that intergalactic travel is impossible.
How many types of galaxy are there?
fourIn 1936, Hubble debuted a way to classify galaxies, grouping them into four main types: spiral galaxies, lenticular galaxies, elliptical galaxies, and irregular galaxies. More than two-thirds of all observed galaxies are spiral galaxies.
What is the oldest type of galaxy?
GN-z11Curious enough, the smallest galaxies are also the elliptical types. The oldest and farthest galaxy ever discovered is an irregular type of galaxy called GN-z11. It is 32 billion light-years / 9.8 billion parsecs away from us. It is estimated that the galaxy formed just around 400 million years after the Big Bang.
How old is our star?
4.603 billion yearsSun/Age
What is the strongest thing in the universe?
These explosions generate beams of high-energy radiation, called gamma-ray bursts (GRBs), which are considered by astronomers to be the most powerful thing in the universe.

How do galaxies die?
In time, any given galaxy begins to run out of recyclable gas. Without gas, it can’t form new stars; the old stars live out their lives and die, and eventually the galaxy dies too. … The galaxies breathe gas in and out, and their stars burn until their gas is gone. Within a galaxy, relatively dense gases fuel star birth.
What is the rarest thing in space?
Now astronomers have spotted a bizarre star that may prove to be one of the rarest objects ever, with maybe as few as five or six of them in the galaxy. The object in question is known as J005311, located in the constellation Cassiopeia about 10,000 light-years from Earth.
What galaxy do we live in?
The Milky WayWe live in one of the arms of a large spiral galaxy called the Milky Way.
What is the hardest thing in the universe?
As substances go, “nuclear pasta” is far from a limp noodle. According to researchers from McGill University, a substance of that name may be the strongest material in the universe. Stronger than steel, diamond, and graphene, nuclear pasta is the material that makes up neutron stars.
What happens once in a lifetime?
Witness a Venus transit It’s a astronomical event which basically encompasses the disk of planet Venus passing across the face of the sun appearing like a little sunspot. It’s advised not to view this sight without proper protection but it occurs only once in 100 years, making it literally once in a lifetime.
What is the most rare blood type?
That means the prevalence of certain blood types varies widely in different parts of the world. However, in the United States, AB-negative is considered to be the rarest blood type, and O-positive the most common.
What is the rarest galaxy?
In the local Universe (within 1 billion light-years of the Solar System), “collisional ring galaxies” are about 1000 times rarer than the internally-created type.

Do you age differently in space?
So depending on our position and speed, time can appear to move faster or slower to us relative to others in a different part of space-time. And for astronauts on the International Space Station, that means they get to age just a tiny bit slower than people on Earth. That’s because of time-dilation effects.
Which galaxy is closest to our own?
Canis Major Dwarf GalaxyThe closest known galaxy to us is the Canis Major Dwarf Galaxy, at 236,000,000,000,000,000 km (25,000 light years) from the Sun. The Sagittarius Dwarf Elliptical Galaxy is the next closest , at 662,000,000,000,000,000 km (70,000 light years) from the Sun.
